Post Installation

Question

When I was downloading the trial version, the installation told me that I had to remove the McAfee Antivirus, as it was conflicting with OneCare. I did this. My system automatically rebooted. I went back into Windows Live OneCare to attempt to complete the installation and it required me to go through a full purchase installation (even though I clicked on "dowload trial"). Now when I reboot, my system is VERY slow. When I try to run OneCare, it tells me that I cannot start it and that I need to contact Customer Service. However, when I do "Ctrl/Alt/Del" and look at the processess that are running, the majority of my CPU usage is going toward a file by the name of "MSMpEng.exe" - which I do not recognize.

Help!

I'm not clear what you mean by a full purchase installation, as there is only one installer. You purchase when you subscribe or activate a subscription (or buy a retail copy and activate).

The first thing I'd recommend is using the McAfee cleanup utility to make sure it is completely gone from your PC.

McAfee Removal Tool - http://www.majorgeeks.com/McAfee_Consumer_Product_Removal_Tool_d5420.html

Then, if OneCare still won't start, see this post for a possible fix - http://forums.microsoft.com/WindowsOneCare/ShowPost.aspx?PostID=2523777&SiteID=2

MSMPENG.EXE is the antimalware engine used by OneCare and Defender. If it is using excessive CPU cycles, that would typically indicate a conflict with other active security software, so that may be resolved by running the McAfee removal tool.

If you continue to have problems, please contact support -
